Best Bottom Feeder Fish For 10-Gallon Tank

Mystery snails


Mystery snails are favorite at-home tanks due to their vibrant shells and peaceful temperament. But little do people know that these snails are also voracious algae eaters.

Mystery snails spend the entire day moving from one place to another on all sides of a tank, chewing on algae and eating it as fast as possible.

Another advantage of having mystery snails as bottom feeders is that these snails do not reproduce too quickly. Their population is easy to control, so you need not worry about snails invading the territory of other tank mates.

Siamese algae eaters

As the name already indicates, Siamese algae eaters make sure your tank is clean and pristine. They are also indiscriminate in their choices of algae, as these fish are comfortable eating brown, green, and red algae colonies.

While algae make up the majority of Siamese algae eaters’ diets, you still have to feed them with other sources of food. Here, anything from frozen pellets to fresh food will suffice.

Cory catfish

The biggest cory catfish does not exceed 4 inches in length, making it ideal for small tanks. They are also docile and peaceful since they spend most of their time wandering at the bottom water layer.

Having a few cory catfish in your home tank ensures the demise of algae, which means your tank will remain fresh and clean for a long time.

Furthermore, cory catfish also feed on protein-rich food. This means that dead fish or leftovers of other tank mates make for a great source of meals. No more worries about spiking ammonia and nitrate levels in your home tank!

Otocinclus catfish

With a tiny size of no more than 2 inches, otocinclus catfish are a great option for 10-gallon tanks. While otocinclus catfish prefer brown algae, they still can feed on other types of varmint.

Since otocinclus catfish are harmless to other animals, they can be at the receiving end of aggressiveness. Therefore, make sure to introduce these bottom feeders to your tank properly. This helps to minimize the chances of collisions and gives your catfish more comfort to explore the tank’s bottom.

Amano shrimp

Invertebrates can easily become bottom feeders if you create the right environment for them. For example, Amano shrimps will not shy away from consuming brown and green algae.

Similar to cory catfish, Amano shrimps are omnivores. Not only do they feed on algae, but they can also take in leftover food. Subsequently, having two or three Amano shrimps in your aquarium is the best way to control and balance the water’s conditions.
